WILLIAM H. SHERMAN, OF NEW YORK, N. Y.

BOTTLE STOPPER.

SPECIFICATION forming part of Letters Patent No. 747,004, dated December 15, 1903.

Application filed March 23 I 1903.

To all whom it ntcty concern:

Be it known that I,WILLIAM H. SHERMAN, a citizen of the United States, and a resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Bottle-Stoppers, of. which the following is a specification.

My invention relates to an improvement in bottle-stoppers, and has for its object to provide a stopper which can be readily locked in position to the neck of the bottle and which may be unlocked therefrom in a very simple and effective manner.

Afurther object is to provide an improvement in the bottle-stopper shown, described, and claimed in my pending application filed July 11, 1902, Serial No. 115,174, whereby the stopper may be secured to the neck of a bottle having a plain interior, the ring to which the cup is secured being adapted to be secured to the exterior of the neck of the bottle.

A practical embodiment of myinvention is represented in the accompanying drawings, in which- Figure 1 represents in vertical central section the upper portion of the neck of a bottle, the parts being in the position which they assume when the cup has been secured to the ring and the ring is in position to be secured to the exterior of the neck of the bottle. Fig. 2 is a similar View showing the ring secured to the exterior of the neck of the bottle for attaching the stopper as a whole thereto. Fig. 3 is a view showing a releasing-plug in its normal position within the cup before the cup is released from its engagement with the ring. Fig. 4 is a view showing the releasing-plug forced inwardly and thereby the cup for re-; leasing the cup from its locking engagement with the ring. Fig. 5 represents the ring in side elevation and top plan. Fig. 6 represents the cup in side elevation and top plan. Fig. 7 represents the cup seated within the ring before it has been locked thereto, the parts being shown in vertical central section; and Fig. 8 represents the cup and ring locked together, the parts being shown in vertical central section.

The neck of the bottleis denoted by 1, and it has a perfectly plain bore.

An annular shoulder 2 is formed around the exterior of the neck of the bottle adjacent Serial No. 149,048. (No model.)

to its top for the attachment of the ring of the stopper to be hereinafter described.

The stopper ring comprises an annular horizontal portion 3, fitted to rest upon the top of the bottle-neck, an inner downwardlyextended tapered flange 4, fitted to enter the interior of the neck of the bottle, and an outer downwardly-extended flange 5, fitted to overlap the exterior of the neck of the bottle. This ring may be stamped or drawn from sheet metal, and the flange 5 before it is crimped inwardly projects a short distance below the shoulder 2 of the bottle-neck when the stopper is in position thereon. A gasket 6 is preferably interposed between the top of the bottle-neck and the horizontal portion 3 of the ring, which gasket is made of some material suitable for the purpose of preventing the leakage of the contents of the bottle.

The stopper-cup comprises a horizontal bottom portion 7, a flaring wall 8, extended upwardly therefrom, and an outwardly-extend ed annular flange -9 at the top of the flaring portion. The flaring portion of the cup is adapted to snugly fit the tapered flange 4 of the ring, and the flange 9 overlaps the horizontal portion 3 of the said ring. The cup may be secured to the ring before the stopper is placed in position on the neck of the bottle. In the present instance I have shown the flange 4 of the ring and the flaring portion 8 of the cup asbeing interlocked by indenting the flange 4 into the said flaring portion, as shown at 10. This indentation may be a circumferential one, which will serve to still further seal the cup and ring together to prevent the escape of gases from within the bottle when the stopper is used in connection with bottle where it is desirable to have an absolute seal.

The stopper is secured to the neck of the bottle by crimping the bottom of the flange 5 of the ring inwardly into engagement with the shoulder 2 on the exterior of the bottleneck, as clearly shown in Fig. 2.

The cup may be released from its locking engagement with the ring when it is desired to remove the stopper by some suitable device-such, for instance, as the releasingplug shown herein. This plug comprises a head portion 11, a shank 12, around which is provided a shallow circumferential groove ICO 13. The shank 12 of the plug is preferably of sufficient diameter to snugly engage the flaring portion 8 of the cup, so that when the plug and thereby the cup are forced inwardly the tapered flange 4 of the ring will be forced outwardly out of locking engagement with the cup. As the plug is forced inwardly the the flange 9 of the cup is drawn into the circumferential groove 13 in the plug, so that when the plug is removed either by internal pressure or by external means the cup and plug will be removed together. The cup is preferably stamped or drawn from some soft metal, so that it can be easily released from the ring by a comparatively slight inwardv pressure of the releasing-plug.

The interlocking arrangement of the cup and ring is such that the internal pressure will serve to more securely seal the two together, because of the pressure having free access to the exterior of the tapered flange 4 ofthe ring. In certain classes of work the cup will be sufficiently secured to the ring by simply forcing it into intimate contact with the tapered flange of the ring. It is furthermore to be understood that it is not essential that the cup be removed from the ring, as in certain instances it might be sufficient to open the stopper to puncture the cup with some suitable device, leaving the cup secured to the ring.

The stopper herein described may be applied to the usual form of bottle-neck.

What I claim is 1. A bottle-stoppercomprising a ring adapted to be secured to the neck of a bottle and a cup secured to said ring.

' 2. Abottle-stoppercomprisingaringadapted to be secured to the exterior of the neck of the bottle and a cup secured to said ring.

3. Abottle-stopper comprisinga ring adapted to be secured to the exterior of the neck of the bottle, a cup secured to said ring and means for releasing the cup from the ring.

4;. A bottle-stopper comprising a ring having a downwardly-extended flange adapted to be secured to the exterior of the neck of the bottle and a cup secured to said ring.

5. A bottle-stopper comprising a ring having an outer downwardly-projected flange adapted to be secured to the exterior of the neck of the bottle and an inner downwardlyextended tapered flange adapted to enter the interior of the neck of the bottle and a cup secured to said tapered flange of the ring.

6. A bottle-stopper comprising a ring adapted to be secured to the exterior of the neck of the bottle, a soft-metal cup fitted to be locked to said ring and a releasing-plug, the said cup and releasing-plug being fitted to be locked together when the cup is released from the ring by the said plug.

7. In combination, a bottle having an annular shoulder, on the exterior of its neck, a ring having a flange adapted to be engaged with said shoulder and a cup secured to said ring.v

In testimony that I claim the foregoing as my invention 1 have signed my name, in presence of two witnesses, this 21st day of March, 1903.

WILLIAM H. SHERMAN.
